Remove the cover and you can measure the ring gear.
Make sure you use the correct fluid in the diff with the correct additive for positraction.

IF I INSTALLED YOU INFO IN THIS SITE CORRECTLY (CHECK ME OR RE-INSTALL)
IF YOU CLICK INTO EACH ONE OF THESE AND VIEW "DETAILS"---MOST TELL WHAT RING GEAR (RG) SIZE IS IN THE DIFFMERELY LOOKING AT THE GASKET SHAPE AND COUNTING BOLT HOLES MAY GET THE INFO YOU WANT WITHOUT DIS-ASSEMBLY
AS FAR AS "DO I HAVE" OR "NOT HAVE" POSI?
THIS COULD VARY FRONT AND REAR (AT LEAST ON JEEPS AND TRUCKS I KNOW) CHECK BOTH ENDS!
JACK THE FRONT UP AND/ OR BACK UP--OR ONE AT A TIME
INSURE YOU ARE IN NEUTRAL--E-BRAKE IS OFF. BE SAFE!
SPIN A WHEEL---IF THE OPPOSITE WHEEL SPINS THE OPPOSITE DIRECTION. YOU HAVE A STANDARD DIFFERENTIAL
IF THE OPPOSITE WHEEL SPINS THE SAME DIRECTION AS YOU ARE TURNING THIS ONE---YOU HAVE POSI. CORRECT ADDITIVE AND VOLUME MUST BE USED
BEING THIS IS 4X4--YOUR HUBS (IF APPLICABLE ON THIS RIG) WILL NEED TO BE LOCKED IN IN ORDER TO MAKE THE OPPOSITE WHEEL MOVE
SORRY--I'M A JEEP CJ KINDA GUY, I DON'T KNOW YOUR SYSTEMS EXACT OPERATION
IF YOU DO HAVE POSI--AFTER YOUR FLUID CHANGE
IF ALL IS GOOD IN THE FLUID DEPARTMENT, SOMETHING THAT WILL AID IN LUBRICATING THE CLUTCHES (KEEPS POPPING NOISES DOWN) IS: FIND AN ABANDONED PARKING LOT,
DRIVE IN REALLY TIGHT FIGURE "8s"
OVER AND OVER (ON A PREVIOUS CJ I HAD, IT TOOK MAYBE 10 "8s")
YOU DO NOT HAVE TO GO FAST. JUST WHAT YOU ARE DOING, WILL DRAW PLENTY ENOUGH ATTENTION. YOU MAY BE EXPLAINING "THE DEAL", TO AN OFFICER, AS I HAD TO DO!
DOING THIS AT NIGHT SORTA MAKES IT LOOK LIKE YOU ARE RECKLESS!--YOUR HEADLIGHTS SORTA MAKE IT LOOK WORSE THAN IT IS!
Check you RPO codes located on your glovebox and it should tell you what you have G80 for locking diff a G80 does not require a friction modifier so a good synthetic gear oil of correct wt. Should do. As far as ring size a 1500 should have a 8an3/4" ring gear. Doing the figure eights sound much more fun though.
